Did You Know?
Kiln has been a part of the English language for over 1,000 years, its first known use in Old English (as "cyline") dating back to the early 700s. Unlike many words that descend from Old English, however, "kiln" is not ultimately Germanic in origin but was borrowed from Latin culina, meaning "kitchen," an ancestor of the English word culinary. In the 14th century, speakers of Middle English began to drop the "n" at the end of the word, and even to this day some English speakers pronounce "kiln" so that it rhymes with "mill." In fact, like "kiln," "mill" (from Late Latin molina) was originally spelled and pronounced with a terminal "n." Unlike "mill," however, "kiln" has retained the final "n" in spelling, if not always in pronunciation.
